This invention relates to a stitch picker and has for its primary object to provide, in a manner as hereinafter` set forth, a device of this character embodying a novel construc- '5' tion and arrangement of parts, for removing the sole securing stitches from a shoe after the outer or top lsole has been removed.

Another important object of the invention is to provide a stitch picker of the character described embodying novel means for automatically feeding the shoe relative to a reciprocating punch when removing the stitches.

Other objects of the invention are to provide a stitch picker of the aforementioned character which will be simple in construction, strong, durable, efficient and reliable in operation and which may be manufactured at low cost. I All of the foregoing, and still further objects and advantages of the invention will become apparent from a study of the followlng specification, taken in connection with the ac-4 companying drawings wherein like charac- .25 ters of reference designate corresponding parts thruout the several views, .and where- 1n:-

Figure 1 is a view in top plan view of a stitch picker constructed in accordance with .30 the present invention.

Fig. 2 is a view in front elevation thereof.

Fig. 3 is a view in end elevation ofthe machine.

Fig. 4 is a view in vertical cross section taken substantially on the line 4-4 of Fig. 2, looking in the direction indicated bythe arrows.

Fig. 5 is a fragmentary view in top plan showlng the arrangement of the shoey engaging element relative to each other. j y

Fig. 6 is a detail view in perspective, of one end portion of the feed rod or device. Y

Referring now to the drawings in detail, it will be seen that the reference numeral 1 designates a base having mounted on one end ortion thereof a pair of standards 2 provided with bearings 3 at their upper ends, in which is journaled a crank shaft 4 having grooved pulleys 5 and 6 xedon its end por tions. The pulley 5 is adapted to bev operatively connected with a suitable source of power (not shown). j

Mounted on the other endy portion of the base 1 is a pair of comparatively short standards k7 having bearingsS at their upper ends in which a crank shaft 9 is journaled. A grooved pulley 1() is fixed `on one end portion of the crank shaft 9. Uprights 11 are mounted on the base 1 adjacent the standards 7, and pivotally mounted between the upper ends of said uprights is a rocker arm 12 having ons end operatively connected/to the crank shaft 9 for actuation thereby through the medium of a connecting rod 13.

A standard 14 is mounted on the base 1 and is provided with a curved upper end portion which terminates in a vertical bearing 15 disposed beneath the other end portion of the rocker arm12. A punch bar 16 is mounted for vertical reciprocation in the bearing 15 and has its upper end portion connected to the adjacent end portion of the rocker arm 12 by a pin and slot connection 17. The lower end portion of the punch bar 16 is socketed for the reception of a punch 19 which is detachably secured in position by a set screw 20.

A pair of comparatively short standards 21 is also mounted on the base 1 inl alinement with the standards 2. The standards 21 are provided with bearings 22 at their upper ends in which a shaft 23 is journalled. A grooved pulley 24 is fixed on one end portion of the shaft 23 and an endless belt 25 is trained over said pulley 24 and the pulley 6V for operatively connecting the shaft 23to vthe crank shaft 4 5 for actuation thereby.

Another grooved pulley 26 is fixed on an intermediate portion of the shaft 23,and an endless belt 27 is trained over said pulley 26 and the pulley 10 on the crank shaft 9 for operatively connecting said crankshaft 9 to. the shaft 23 for actuation thereby. A brush 28 which preferably is provided with metal bristles Vis fixed on the other end portion of the shaft 23 for rotation adjacent the punch 95 19.

A work supporting table 29 is disposed ad- 'acent the punch 19 on a supportingleg 30 whichis secured to the base 1. The table 29 is adapted for vengagement with the welt the clamping arm .31 Vfor yieldingly urging` Y said clamping armagainst th'esh'oe'.

The reference numeral 34 designates a;

guardr which is disposed adjacent the brush 28and the punch 19, said guard beingrmount ed on the upper end of a supporting leg 3 5 which is mounted on the base-1.

A feed rod 36 is mounted for horizontal reciprocation on the base 1 in the brackets 37. A feed finger 38 is formed on one. end of the feed ,rod 36, said feed finger terminating in a pointed free end portionadapted for engagement with the shoe in a manner to feed said shoe in one direction across the table 29 beneath the punch 19. At its other end, the feed rod 36 terminates in an end portion 39 Y of polygonalcross section having a series Y said of threaded openings 40 extendingV transversely therein in which a pin 41 is selectively insertible. Y

The pin 41, 'of course, pro-jects'from one side of the polygonal portion 39 then hasits free ends provided with a slot for receiving a suitable tool such as a screw driver, for placing pin in the openings 40, or removing said pin therefrom. A bell crank lever 42 is mounted for swinging movement in a. vertical plane on a bracket 43. A connecting rod 44 operatively'connects the bell crank lever 42 to the `crank shaft 4 for actuation thereby through the medium of a hinged free end kportion 45 having ay pin and slot connection'46 with the bell crank lever. The other arm of the bell crank lever is arcuate and the free end portion thereof is adapted for engagement with the pin 41 for actuating the feed rod 36 in one direction. j j Y A coiled spring 47 has one end 'connected to the free end of the portion 39 of the feed rod 36, and 'its other end connected tofabrac-ket 48 on the base 1 for yieldingly urging the feed rod 36 in the opposite direction. Y

When the machine is use, the feed finger 38 engages the welt of the shoe and moves said shoe racross the't-able 29 beneath the punch 19 in. an alternating or step by step fashion for disposing' the holes throughwhich the stitches pass properly beneath the punch 19, aswill be understood. The brush 28"'removes the threads which may cling to theshoe after 'being punched out of the holes, by the eles ment 19.

It may be well to here calll attention tothe fact that the standards 2 are curvedat their upper end portions a manner similar to the standard 14.l
